That's old school effective. I've been to countries where they put long bolts of cloth in towers with open/ ventilated tops that pushed the cool air into the structure and allowed for hot air to escape. Been doing it for thousands of years and it still works. Cheers

It's 100 plus now. My AC unit broke and this DIY cooler hack saved the day!
-
You saved my life - moved into a manufactured home and the a/c system is still being worked on and the heat hit Las Vegas earlier than it should have!!! Life saver!!!

Great idea! Could dry your laundry this way too, and you'd be multi-tasking :)

Our friends in Europe could really use this tutorial right now. :)

WOW! We don't have many hot days in the west coast of Canada so most of the buildings don't come with AC, although recently we've been hit with many bad heat waves, last year we had ~700 people die from a sudden record-breaking 49.6C (121F) heat dome, and this year we're having one of the longest stretch of hot weathers. I'm so lucky to come across your video, this literally can save lives. Thank you so much for sharing!

This is awesome! I just did this with some laundry and I wondered if anyone else had done this. Such a great idea, after the laundry is dry I think I'm going to wet some towels like you did!

Low tech A/C ! Makes perfect sense.
-
Saw this on Reddit and sent it on to friends in the UK right now. Thanks!
-
Heck of a lot easier than diy'ing something, especially in the UK where it's only unbearable for a few weeks or so. Many thanks!

This would work soo much longer, and with less upkeep, if one end of those towels was resting in a bin of water, as it will naturally wick along the fibers, keeping it wet as long as the bin has water in it. Cotton and nylon are the best for wicking water.

Wow! Fantastic. Our A/C went out the height of the day in Phoenix. A cool 106! Was ready to hit friends or a hotel. But decided to give this a try. A fan, a couple of wet towels, and a foldable double-wide bed frame. Working like a charm. After watching a couple episodes of Survivorman last week, this ain't nothing. LOL. Gonna rough it out!! Thanks so much for sharing!!

This evap method is great for killing stale heat in a room, all you need is to place one unit at higher elevation at least overnight and it works just as good as a cheap air conditioner. I didn't have much props to hold the cloth so on mine I just wrapped the fan with 2 wet boxing handwraps, and left space at the bottom of the fan for the cold air to sink. Getting a thermostat to benchmark the results too but already noticing the difference after leaving it running overnight.

Thanks! All stuff I have in this room with me, already. Better than when I tried the fan over a hole in an ice chest lid and the fan almost fell in, while plugged in.

You sir. Have just saved my life. I have my hat off to you. I just did this. And it's pretty amazing.
-
Nice video for those that live in the desert, but as a Florida man, swamp coolers aren't really an option.
-
This is an amazing trick. Alas it is way too humid where I live for this to work.
-
I usually just drape the towel over the back of the fan with a bowl or container of water sitting on the floor and towel dipped in to keep it going for longer. It also works better when more of the air is being drawn through the towel.

when i was younger and living in southern california , i d take a fan and a pot or a small caserloe dish , put water in it and would cool the room. as a small boy and living in ohio usa , my dad would take a wet sheet and put it on the casement window with a fan in front of it to cool is room. yes i know ohio is humid

I'll try it if ever gets that warm. We've had a cool summer, which is odd. Might end up with a summery autumn.
